Intensive care of traumatic brain injury and aneurysmal subarachnoid hemorrhage in Helsinki during the Covid-19 pandemic

Outcome of early rehabilitation of patients with traumatic brain injury during COVID-19 pandemic in The Republic of Srpska, Bosnia and Herzegovina

Introduction

The COVID-19 pandemic has placed a tremendous burden on the healthcare system. Patients with traumatic brain injury (TBI) have to get fast track treatment which is independent of environmental conditions. The aim of this study was to investigate epidemiological and clinical outcomes of early rehabilitation and compare it with the literature data during the non-COVID-19 period.

Materials and methods

A retrospective study included 174 patients with TBI, average 57 ± 19.08 years. They all underwent treatment in the University Clinical Center, Republic of Srpska, Bosnia and Herzegovina during the period January-December 2021. We have analyzed the epidemiological data and clinical course in 174 patients as well as the outcome of early rehabilitation in 107 patients. In clinical evaluation were used: Glasgow Coma Score (GCS), Functional Independence Measure (FIM) and Barthel Index on admission and at discharge, as well as Glasgow Outcome Scale (GOS) at discharge. ANOVA, SPANOVA, Student t-test and Pearson correlation coefficient were used in statistical analysis. The value (p < 0.05) was used for statistical significance.

Results

A total of 174 patients with TBI were included in this study. Most of the patients (n = 94) were older than 60, male (n = 125) and the most frequent cause of TBI was falling over (n = 88). About a half (n = 92) had a mild TBI, almost one third of the sample had moderate (n = 52), while only 30 patients had severe TBI. Total of 139 (80.3%) patients had the improved outcome, the worsening was registered in 2 (1.2%), while the fatal outcome was reported with 33 (18.5%) patients. When comparing the scores on admission and at discharge, the improvement of mean parameter values was reported for GCS (9.9 vs. 14.1), for Barthel Index (57.25 vs. 86.85), and for FIM (67.35 vs. 105.15), (p < 0.001). A complete recovery at discharge was found in 63.79%, a mild deficit in 8.62%, while serious deficit was found with 6.32%, and vegetative state with 2.29% patients.

Conclusion

The COVID-19 pandemic had a significant effect on the epidemiological data but not on the clinical outcome of patients with TBI. Early rehabilitation proved to be effective and to contribute to positive treatment outcome.

Subarachnoid hemorrhages and aneurysms during the SARS-CoV2-pandemia at a tertiary medical center - Analysis of incidence and outcome

Introduction

During the COVID-19-pandemic a significant decrease of up to 13% of all kinds of medical emergencies was reported. Similar trends were expected for aneurysmal subarachnoid hemorrhages (aSAH) and/or symptomatic aneurysms.

Research question

To analyze a correlation of the SARS-CoV2-infection and the incidence of aSAH, and to assess the impact of the pandemic-lockdown on the incidence, the outcome and the course of patients suffering from aSAH and/or aneurysms.

Material and methods

From March 16th, 2020 (first lockdown in Germany) to January 31st, 2021, all patients admitted to our hospital were screened by polymerase-chain-reaction (PCR) test for genetic material of SARS-CoV2. During this period, aSAH and symptomatic cerebral aneurysms were assessed and retrospectively compared to a historic longitudinal case-cohort.

Results

Of 109.927 PCR-tests, 7.856 (7.15%) revealed a SARS-CoV2-infection. None of the patients mentioned above were tested positively. The number of aSAH and symptomatic aneurysms rose by 20.5% (39 vs. 47 cases) (p ​= ​0.93). Poor grade aSAH, as well as extensive bleeding-patterns were more often observed (p ​= ​0.63 and p ​= ​0.40, respectively), with more symptomatic vasospasms diagnosed (5 vs. 9 patients). Mortality rate increased by 8,4%.

Discussion and conclusion

A correlation between SARS-CoV2-infection and the incidence of aSAH could not be established. Still, the overall number and the number of poor-grade aSAHs increased as well as symptomatic aneurysms during the pandemic. Therefore, we might conclude that dedicated neurovascular competence should be retained in designated centers to care for these patients even or especially in special situations affecting the global healthcare system.

Trends in Emergency Department Visits and Surgeries due to Traumatic Brain Injury During the COVID-19 Pandemic in Finland

We aim to evaluate the changes in the incidence of TBI, trauma craniotomies, and craniectomies during the COVID-19 pandemic in Finland. This retrospective register study was conducted at three Finnish hospitals. We retrieved the numbers of emergency department (ED) visits, inpatient admissions, and trauma craniotomies and craniectomies due to TBI in the adult population from 2017 to 2020.We calculated the incidences per 100 000 inhabitants and compared the year 2020 to the reference years (2017-2019) by incidence rate ratios (IRR) with 95% confidence intervals. The incidence of TBI-related ED visits during the study period compared to the reference years started to decrease in March 2020 (IRR 0.86, CI: 0.73-1.02), and the lowest incidence was seen in April 2020 (IRR 0.83, CI: 0.68-1.01). The incidence of ED visits showed a second decrease in December (IRR 0.80, CI: 0.67-0.96). The incidence of concussion decreased during the national lockdown in March (IRR 0.80, CI 0.66-0.97). The incidence of ED visits due to TBI decreased after the declaration of national lockdown in spring 2020 and showed a second decrease during regional restrictions in December. In addition, the incidence of neurosurgically treated TBI decreased during restaurant restrictions in the spring.

Traumatic Brain Injury during the SARS-CoV-2 Pandemics in Slovenia: A Single Center Study

(1) Background: The SARS-CoV-2 pandemic had a significant impact on the management of traumatic brain injury (TBI). We aimed to compare the clinical characteristics and outcomes of TBI patients before and during the SARS-CoV-2 pandemic.; (2) Methods: We analyzed depicted data from existing medical records on sex, age, mechanism of injury, clinical performance at admission and discharge, neuroimaging, laboratory values at admission, mortality, duration of hospitalization, and referrals after discharge from the traumatology department for all adult patients during the SARS-CoV-2 pandemic and a year before. Variables were compared using the Chi-square or t-test between both groups.; (3) Results: Most patients had mild (n = 477), followed by moderate (11) and severe (11) TBI. Mild TBI was less frequent during the SARS-CoV-2 period (n = 174 vs. n = 303). The incidence of high falls increased during the SARS-CoV-2 period (14.5% vs. 24.7%; p < 0.05) in the group with mild TBI. Patients had similar mean Glasgow Coma Scales (GCS), Glasgow Outcome Scales-Extended (GOSE), and glucose levels at admission before and during the pandemic. Serum ethanol levels were significantly lower during the SARS-CoV-2 period (1.3 ± 0.7 mmol/L vs. 0.7 ± 1.2 mmol/L; p < 0.001). At discharge, the mean GCS was significantly lower (14.7 ± 1.8 vs. 14.1 ± 0.5; p < 0.05) for patients treated during the SARS-CoV-2 period than before the SARS-CoV-2 period. There were no differences in GOSE; (4) Conclusions: our results demonstrated a significant impact of SARS-CoV-2 pandemic on the frequency, mechanism, and consequences of TBI, and may help improve care for our patients.

The Increased Mortality Rate with Lower Incidence of Traumatic Brain Injury during the COVID-19 Pandemic: A National Study

Background: the COVID-19 pandemic with the following lockdown strategies have affected virtually all aspects of everyday life. Health services all over the world faced the crisis on an unprecedented scale, hampering timely care delivery. The present study was designed to assess the impact of the COVID-19 outbreak on the incidence and treatment of traumatic brain injuries in Poland. Methods: the data on hospital admissions with traumatic brain injuries as the primary diagnosis were extracted from the National Health Fund of Poland. For the purpose of this study, the search was limited to four relevant diagnosis-related groups. The overall in-house mortality was calculated. Results: there were 115,200 hospitalizations due to traumatic brain injury identified in the database. Overall, in comparison with the average of six prior years, in 2020 the volume of patients with traumatic brain injury dropped by 24.68% while the in-house mortality rate was increased by 26.75%. Conclusions: the COVID-19 pandemic with the resulting lockdown caused a radical reduction in human mobility. It had a profound impact on the incidence of traumatic brain injury, which dropped significantly. At the same time, the mortality rate increased drastically.

Health Care Implications of the COVID-19 Pandemic for Patients with Severe Traumatic Brain Injury-A Nationwide, Observational Cohort Study

BACKGROUND

Containment measures during the coronavirus disease of 2019 (COVID-19) pandemic have resulted in a substantial reduction in treatment of injury. The effect of the COVID-19 pandemic on the epidemiology and mortality of severe traumatic brain injury on a national, population-based level is unknown.

METHODS

Data on all patients with severe traumatic brain injury between 2017 and 2020 were retrieved from the National Trauma Registry of Norway. The study cohort was derived from the pandemic period (March 12 to December 31, 2020) and the control cohort from the prepandemic years 2017 to 2019. The outcome measures were 30-day mortality, in-hospital mortality, and discharge destination.

RESULTS

This study included 522 trauma patients with severe traumatic brain injury, 387 (74.1%) in the prepandemic and 135 (25.9%) in the pandemic period. Length of stay increased significantly during the pandemic period (4 vs. 3 days; P = 0.014). The 30-day mortality rate was 39% (n = 149) in the prepandemic versus 38% (n = 52) pandemic period (P = 0.998). In-hospital mortality was 33% (n = 128) in the prepandemic versus 33% (n = 44) in the pandemic period (P = 0.920). There were no statistically significant differences in discharge destination besides the number of patients discharged to home in the pandemic period (P = 0.003). When adjusted for clinical relevant factors such as age, gender, and head injury severity, the mortality outcomes did not change during the pandemic period.

CONCLUSIONS

The containment and lockdown measures during the COVID-19 pandemic in Norway did not affect the number of patients or mortality of patients with severe traumatic brain injury.

Acute ischemic stroke and COVID-19 pandemic in Brazil: a comparative study of frequency and risk factors before and during SARS-CoV-2 era

Background

COVID-19 pandemic directly impacted the request for hospital care and medical assistance for several diseases worldwide, as occurred with acute ischemic stroke. The present study sought to compare the incidence and severity of acute ischemic stroke (AIS), in addition to sociodemographic, clinical, and radiological characteristics of patients hospitalized in the prepandemic (2018–2019) and pandemic (2020–2021) eras.

Methods

An incidence case–control, observational, and analytical research was carried out in the Stroke Unit of Hospital Governador Celso Ramos, Florianopolis, Santa Catarina, Brazil, including 171 patients admitted with acute ischemic stroke from April 2018 to April 2019 (prepandemic era) and 148 patients between January 2020 and January 2021 (during pandemic).

Results

The mean incidence of AIS hospital admissions was significantly lower in the pandemic period (CI 95%, 0.2 to 5.6; p = 0.04), being lower in the lockdown periods and when the incidence of new COVID-19 cases increased. Besides, referring to AIS severity, the mean areas of AIS were larger during the pandemic period (p < 0.01), especially in August, September, December, and January (p < 0.05). Sociodemographic and clinical variables did not show any difference between the two periods of the study.

Conclusions

Hospital admissions for AIS decreased in the COVID-19 pandemic, mostly during months of higher incidences of new COVID-19 cases. When the incidence of admissions diminished, an increase in the severity of AIS was observed, characterized by larger areas. These findings might contribute to other similar referral centers in managing public policies related to stroke.

Global impact of the COVID-19 pandemic on subarachnoid haemorrhage hospitalisations, aneurysm treatment and in-hospital mortality: 1-year follow-up

BACKGROUND

Prior studies indicated a decrease in the incidences of aneurysmal subarachnoid haemorrhage (aSAH) during the early stages of the COVID-19 pandemic. We evaluated differences in the incidence, severity of aSAH presentation, and ruptured aneurysm treatment modality during the first year of the COVID-19 pandemic compared with the preceding year.

METHODS

We conducted a cross-sectional study including 49 countries and 187 centres. We recorded volumes for COVID-19 hospitalisations, aSAH hospitalisations, Hunt-Hess grade, coiling, clipping and aSAH in-hospital mortality. Diagnoses were identified by International Classification of Diseases, 10th Revision, codes or stroke databases from January 2019 to May 2021.

RESULTS

Over the study period, there were 16 247 aSAH admissions, 344 491 COVID-19 admissions, 8300 ruptured aneurysm coiling and 4240 ruptured aneurysm clipping procedures. Declines were observed in aSAH admissions (-6.4% (95% CI -7.0% to -5.8%), p=0.0001) during the first year of the pandemic compared with the prior year, most pronounced in high-volume SAH and high-volume COVID-19 hospitals. There was a trend towards a decline in mild and moderate presentations of subarachnoid haemorrhage (SAH) (mild: -5% (95% CI -5.9% to -4.3%), p=0.06; moderate: -8.3% (95% CI -10.2% to -6.7%), p=0.06) but no difference in higher SAH severity. The ruptured aneurysm clipping rate remained unchanged (30.7% vs 31.2%, p=0.58), whereas ruptured aneurysm coiling increased (53.97% vs 56.5%, p=0.009). There was no difference in aSAH in-hospital mortality rate (19.1% vs 20.1%, p=0.12).

CONCLUSION

During the first year of the pandemic, there was a decrease in aSAH admissions volume, driven by a decrease in mild to moderate presentation of aSAH. There was an increase in the ruptured aneurysm coiling rate but neither change in the ruptured aneurysm clipping rate nor change in aSAH in-hospital mortality.

Non-COVID outcomes associated with the coronavirus disease-2019 (COVID-19) pandemic effects study (COPES): A systematic review and meta-analysis

BACKGROUND

As the Coronavirus Disease-2019 (COVID-19) pandemic continues, healthcare providers struggle to manage both COVID-19 and non-COVID patients while still providing high-quality care. We conducted a systematic review/meta-analysis to describe the effects of the COVID-19 pandemic on patients with non-COVID illness and on healthcare systems compared to non-pandemic epochs.

METHODS

We searched Ovid MEDLINE/EMBASE/Cochrane Database of Systematic Reviews/CENTRAL/CINAHL (inception to December 31, 2020). All study types with COVID-pandemic time period (after December 31, 2019) with comparative non-pandemic time periods (prior to December 31, 2019). Data regarding study characteristics/case-mix/interventions/comparators/ outcomes (primary: mortality; secondary: morbidity/hospitalizations/disruptions-to-care. Paired reviewers conducted screening and abstraction, with conflicts resolved by discussion. Effect sizes for specific therapies were pooled using random-effects models. Risk of bias was assessed by Newcastle-Ottawa Scale, with evidence rating using GRADE methodology.

RESULTS

Of 11,581 citations, 167 studies met eligibility. Our meta-analysis showed an increased mortality of 16% during the COVID pandemic for non-COVID illness compared with 11% mortality during the pre-pandemic period (RR 1.38, 95% CI: 1.28-1.50; absolute risk difference: 5% [95% CI: 4-6%], p<0.00001, very low certainty evidence). Twenty-eight studies (17%) reported significant changes in morbidity (where 93% reported increases), while 30 studies (18%) reported no significant change (very low certainty). Thirty-nine studies (23%) reported significant changes in hospitalizations (97% reporting decreases), while 111 studies (66%) reported no significant change (very low certainty). Sixty-two studies (37%) reported significant disruptions in standards-to-care (73% reporting increases), while 62 studies (37%) reported no significant change (very low certainty).

CONCLUSIONS

There was a significant increase in mortality during the COVID pandemic compared to pre-pandemic times for non-COVID illnesses. When significant changes were reported, there was increased morbidity, decreased hospitalizations and increased disruptions in standards-of-care.

Estratégias organizacionais no centro cirúrgico diante da pandemia de COVID 19: uma revisão integrativa

Introdução: os sistemas de saúde foram desafiados a desenvolver estratégias organizacionais para a prestação de cuidados cirúrgicos. Objetivo: apresentar as estratégias dos serviços de saúde no que se refere às práticas de cuidados cirúrgicos em tempos de pandemia de COVID-19. Materiais e métodos: revisão integrativa, desenvolvida em seis etapas, cuja busca dos artigos ocorreu na Biblioteca Virtual de Saúde, SciELO, PubMed e ScienceDirect. Os descritores controlados em saúde adotados foram “Centros Cirúrgicos” e “Infecções por Coronavírus”, de acordo com os sistemas DeCS e MeSH Terms. Foram selecionados 60 artigos de 405 estudos encontrados. Resultados: as principais estratégias utilizadas pelos serviços de saúde foram: a suspensão e adiamento de cirurgias eletivas durante as ondas de contágio da doença; e a triagem cuidadosa dos pacientes para COVID-19 antes e após intervenções cirúrgicas. Discussão: a suspensão e o adiamento de cirurgias eletivas devem ser avaliados com cautela pela equipe de saúde, de forma individualizada, para cada paciente, visto que situações clínicas não urgentes podem agravar ao longo do tempo, aumentando as chances de morbimortalidade desses pacientes. Conclusão: a triagem dos pacientes e dos profissionais da saúde para COVID-19 são estratégias importantes para evitar a contaminação desses sujeitos. A suspensão e o adiamento de cirurgias eletivas, durante as ondas de contágio por COVID-19, são recomendados para aumentar a capacidade de leitos disponíveis para pacientes graves hospitalizados por essa doença. Essa recomendação também auxilia no remanejamento de profissionais desse setor para as unidades com a demanda de cuidados de saúde mais elevada.

Epidemiological Pattern of Traumatic Brain Injury in the COVID-19 Pandemic: A Systematic Review and Meta-Analysis

Background

Although the incidence of traumatic brain injury (TBI) has decreased since the beginning of the coronavirus disease 2019 (COVID-19) pandemic and severe acute respiratory syndrome coronavirus 2 is still evolving, the number of TBI cases has still greatly increased in multiple countries. In the present systematic review and meta-analysis, we evaluated the epidemiological characteristics of patients with TBI before and during the COVID-19 pandemic.

Methods

We conducted a systematic literature search of original studies, short reports, and research letters from databases on studies that contained data about the severity, mortality, presence of neurological deficits, radiological diagnosis, cause of injury, and type of management of TBI during a specified period within the pandemic compared with before the pandemic.

Results

A total of 18,490 subjects from 13 studies were included in the present study. The results of the meta-analysis showed a higher TBI mortality rate during the COVID-19 pandemic in the low-to-middle income countries (odds ratio, 1.65; 95% confidence interval, 1.12–2.41; P < 0.05; I² = 40.8%; P = 0.18). The proportion of subdural hemorrhage was decreased, and the proportion of subarachnoid hemorrhage was increased in low- to middle-income and high-income countries, respectively. The proportion of assaults as the cause of TBI had increased during the pandemic (odds ratio, 1.40; 95% confidence interval, 1.06–1.86; P = 0.02; I² = 20.8%; P = 0.28). We did not find any significant differences in the incidence of surgical intervention for TBI during the pandemic.

Conclusions

Our results have indicated that during the COVID-19 pandemic, the TBI mortality rate had increased in low- to middle-income countries. The rate of assault as the cause of TBI had also increased during the pandemic.

Challenges for maintaining surgical care practices in the COVID-19 pandemic: an integrative review

OBJECTIVES

To present the knowledge produced on challenges of health services for maintaining surgical care practices in times of the COVID-19 pandemic.

METHODS

This is an integrative literature review, performed with descriptors 'Operating rooms' and 'Coronavirus Infections' in the MEDLINE/PubMed Central, IBECS, LILACS, BDENF, Coleta SUS, BIGG, BINACIS, SciELO, PubMed, Science Direct, and Cochrane Library databases.

RESULTS

Of the 405 studies analyzed, 27 met the inclusion criteria. The main challenges for surgical services during the pandemic were: (i) rearrangement of general practice in surgical units; (ii) administration and management of resources and elective surgeries; (iii) follow-up and control of preoperative patients to medium term; (iv) maintenance of patients' and health professionals' autonomy and mental health in this context; and (v) teaching health residents in the operating room.

CONCLUSIONS

For surgical care services, the challenges caused by managing the high demand of patients in need of care resulted in the transfer of own resources to other units and the consequent hiring of professionals to meet the demand for these services due to the damming of postponed elective surgeries. This knowledge will allow us to propose strategies in decision making in this scenario, considering the new waves that may arise from this disease.

Impact of COVID-19 pandemic on haemorrhagic stroke admissions: a systematic review and meta-analysis

BACKGROUND AND PURPOSE

COVID-19 pandemic, a global health crisis, is disrupting the present medical environment. This systematic review and meta-analysis aimed to evaluate the impact of the COVID-19 pandemic on stroke hospitalisations, especially haemorrhagic stroke.

METHODS

The EMBASE, PubMed, Web of Science, Elsevier, Medline, Cochrane Library and Google Scholar electronic databases were searched for all relevant studies. Two researchers independently screened the studies, extracted data and assessed the quality of the included studies. Odds ratio (OR), total events, OR and 95% CI were considered as the effect size. A fixed-effects model was used to pool the study-specific estimate. The present study was performed by using Review Manager (V.5.3.0) software. We assessed the risk of bias using the Newcastle-Ottawa Scale.

RESULTS

A total of 17 studies with 14 445 cases were included. Overall, the number of stroke admissions is lower in the pandemic period versus the control period (6252 vs 8193). The difference of haemorrhagic stroke is significant, with 1233 of 6252 cases in the pandemic group and 1621 of 8193 cases in the control group. Intracerebral haemorrhage is present in 461 of 1948 cases in the pandemic group and 618 of 2734 cases in the control group. As for subarachnoid haemorrhage, the difference between the two groups is significant, with 70 of 985 cases in the pandemic group and 202 of 1493 cases in the control group.

CONCLUSIONS

The number of stroke admissions is lower in the pandemic period compared with the control period. There is a higher rate of haemorrhagic stroke in the pandemic period. Subgroup analysis identifies a significant increase in the occurrence of intracerebral haemorrhage in the pandemic period. Due to limited data and the impact of a single article, the impact of COVID-19 pandemic on subarachnoid haemorrhage is unclear.

Declining Numbers of Neurosurgical Emergencies at a German University Medical Center during the Coronavirus Lockdown

BACKGROUND

 The coronavirus pandemic due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is posing unprecedented challenges to health care systems around the globe. Consequently, various lockdown scenarios have been politically imposed to get control over the spread of this disease. We examined the impact of the lockdown situation on the number of neurosurgical emergency patients admitted to our tertiary care center with a catchment area of ∼2.2 million inhabitants in the south of Germany to ensure adequate neurosurgical emergency care during a pandemic lockdown.

METHODS

 All emergency admissions (with consecutive inpatient treatment) to the Department of Neurosurgery at the University Medical Center Regensburg, Germany, between March 1 and May 8 (69 days) of the years 2018, 2019, and 2020 were retrospectively identified and reviewed for this study. Demographic data, diagnoses, urgency of surgery, and duration of the journey to the emergency room were examined.

RESULTS

 Between March 1 and May 8, 2020, 59 emergency patients were neurosurgically treated at our department. Compared with 2018 and 2019, emergency admissions in 2020 had thus declined by 37.2 and 27.1%, respectively. Regarding the year 2020, we found a significant drop from 1.71 and 1.52 emergency patients per day in January and February 2020, respectively, to 0.86 during lockdown (p < 0.001). The decline especially concerned nontraumatic spinal cases and also patients with other neurosurgical diagnoses such as intracranial hemorrhage. Evaluation of the overall disease severity of admitted patients by means of the urgency of surgery showed no difference between the baseline years and the lockdown period.

CONCLUSION

 Our findings are in line with other observational studies of neurosurgical, neurologic, and cardiologic centers in Europe that have described a drop in emergency cases. The reasons for this drop that seems to affect various medical fields and countries across Europe are still unidentified. Morbidity and mortality rates are still unknown, and efforts should be made to facilitate neurosurgical emergency care during a pandemic lockdown.

Effects of β-Blockers on the Sympathetic and Cytokines Storms in Covid-19

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a causative virus in the development of coronavirus disease 2019 (Covid-19) pandemic. Respiratory manifestations of SARS-CoV-2 infection such as acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) leads to hypoxia, oxidative stress, and sympatho-activation and in severe cases leads to sympathetic storm (SS). On the other hand, an exaggerated immune response to the SARS-CoV-2 invasion may lead to uncontrolled release of pro-inflammatory cytokine development of cytokine storm (CS). In Covid-19, there are interactive interactions between CS and SS in the development of multi-organ failure (MOF). Interestingly, cutting the bridge between CS and SS by anti-inflammatory and anti-adrenergic agents may mitigate complications that are induced by SARS-CoV-2 infection in severely affected Covid-19 patients. The potential mechanisms of SS in Covid-19 are through different pathways such as hypoxia, which activate the central sympathetic center through carotid bodies chemosensory input and induced pro-inflammatory cytokines, which cross the blood-brain barrier and activation of the sympathetic center. β2-receptors signaling pathway play a crucial role in the production of pro-inflammatory cytokines, macrophage activation, and B-cells for the production of antibodies with inflammation exacerbation. β-blockers have anti-inflammatory effects through reduction release of pro-inflammatory cytokines with inhibition of NF-κB. In conclusion, β-blockers interrupt this interaction through inhibition of several mediators of CS and SS with prevention development of neural-cytokine loop in SARS-CoV-2 infection. Evidence from this study triggers an idea for future prospective studies to confirm the potential role of β-blockers in the management of Covid-19.

Neurotrauma admissions and COVID-19: a National Centre experience

Background

To investigate the impact of COVID-19 on trauma admissions to a National Neurosurgical Centre in Ireland.

Methods

Retrospective analysis of a prospectively maintained database of all trauma admissions to the National Neurosurgical Centre at Beaumont Hospital, Dublin, during the period March 1 to May 31, 2019 and 2020. Primary outcome was 30-day mortality rate. Secondary outcomes included time transfer time, time from admission to time of surgery, and intensive care unit (ICU) admissions. Patients under the age of 16 were excluded.

Results

A total of 32 and 39 patients were admitted to the National Neurosurgical Centre following trauma over the 3-month period in 2020 and 2019 respectively, giving a 17.9% reduction in admissions. The 30-day mortality rate increased from 7.7% in 2019 to 15.6% on 2020 (p = 0.45). Mean transfer time was 4 h 58 min in 2019 and 3 h 55 min in 2020 (0.22). Mean time from admission to time of surgery was 9 h 10 min in 2019 and 5 h 37 min in 2020 respectively (p = 0.35). In 2019, 20 patients (51.3%) were admitted to ICU. This increased to 23 patients (69.7%) in 2020 (p = 0.08).

Conclusions

Traumatic brain injury 30-day mortality rates increased during the first COVID-19 lockdown period. Trauma admission rates to ICU remained unchanged despite an overall reduction in trauma admissions. Transfer time, time to surgery, and length of stay were impacted by COVID-19. Despite the challenges COVID-19 has posed, it is important to maintain a fully functioning neurosurgical and neurocritical care service during the pandemic.

The Impact of the COVID-19 Pandemic on Traumatic Brain Injury Management: Lessons Learned Over the First Year

The COVID-19 pandemic has had widespread consequences on health care systems around the world. It resulted in extensive changes to the referral patterns, management, and rehabilitation of surgical conditions. We aimed to evaluate the effect the COVID-19 pandemic has had on traumatic brain injury (TBI) specifically. We reviewed the literature published on COVID-19 and TBI referrals, management, and rehabilitation. Significant changes were seen in the referral patterns of TBIs worldwide, explained by changes in societal behaviors and changes in the mechanism of injury. Implementation of strict infection control measures and COVID-19 screening was commonplace, with some reporting changes to operating room protocols. TBI was more likely to be conservatively managed. Rehabilitation services were restricted, with a greater shift towards telemedicine to provide rehabilitative therapy remotely.

Comparative Analysis of COVID-19 Outbreak and Changes in Neurosurgical Emergency Patients

Objective

COVID-19 has spread worldwide since the first case was reported in Wuhan, China, in December 2019. Our institution is a regional trauma and emergency center in the northern Gyeonggi Province. The changing trend of patient care in the emergency room of this hospital likely reflects the overall trend of patients in the area. In the present study, whether changes in the surrounding social environment following the outbreak of COVID-19 changed the incidence of neurosurgical emergency patients and whether differences in practice existed were investigated.

Methods

The overall trend was analyzed from January 2020 which is before the outbreak of COVID-19 to September 2020. To remove bias due to seasonal variation, the previous 2 year's records during the same period were reviewed and compared. Confirmed COVID-19 patients in the northern Gyeonggi Province were identified using data released by the government. And patients who came to the emergency department with head trauma and stroke were identified.

Results

Based on the present study results, the total number of neurosurgery emergency patients decreased over the study period. In the trauma patient group, the number of patients not involved in traffic accidents significantly decreased compared with patients involved in traffic accidents. Among the stroke cases, the rate of ischemic stroke was lower than hemorrhagic stroke, although a statistically significant difference was not observed. Meanwhile, an increase in the risk of mortality associated with trauma or stroke cases was not observed during the COVID-19 outbreak compared with the same time period in the previous year.

Conclusion

Due to the occurrence of COVID-19, non-essential activities have decreased and trauma cases not associated with traffic accidents appeared to decrease. Due to the decrease in overall activity, the number of stroke patients has also decreased. This trend is expected to continue even in the post-COVID-19 era, and accordingly, the results from the present study are relevant especially if the current situation continues.

Analyzing outcomes of neurosurgical operations performed before and during the COVID-19 pandemic in Egypt. A matched single-center cohort study

Background

Since the emergence of the first COVID-19 case in Wuhan, the virus affected several health care systems. Globally, the COVID-19 has a transforming effect on health care provision. Substantial evidence was clear that the global surgical services were impacted. The field of neurosurgery was primarily affected, and most elective surgeries were suspended. There are no current reports from Egypt that describe the mortality outcome of neurosurgical procedures in the context of the pandemic.

Methods

We performed that study at a large tertiary center in Egypt (Cairo University Hospital). It is a single-center matched cohort study.

Results

Our results examined about 346 patients earlier during the COVID-19 pandemic. About 46 (13.29%) were unmatched, so we excluded them from the final analysis of the data. About 300 patients' were matched to 304 patients' before the pandemic in 2019. The mortality outcome of neurosurgical interventions was higher during the pandemic.

Conclusions

Amid the COVID-19 pandemic, the mortality outcome of neurosurgical procedures was higher than on regular days at our center. The anesthesia time was prolonged while the operation time was shortened. We strongly suggest further multicenter studies to assess the effect of COVID-19 on neurosurgical mortality and functional outcome.

Decreased number of deaths related to severe traumatic brain injury in intensive care unit during the first lockdown in Normandy: at least one positive side effect of the COVID-19 pandemic

Background

The COVID-19 pandemic has led to severe containment measures to protect the population in France. The first lockdown modified daily living and could have led to a decrease in the frequency of severe traumatic brain injury (TBI). In the present study, we compared the frequency and severity of severe TBI before and during the first containment in Normandy.

Methods

We included all patients admitted in the intensive care unit (ICU) for severe TBI in the two tertiary neurosurgical trauma centres of Normandy during the first lockdown. The year before the containment served as control. The primary outcome was the number of patients admitted per week in ICU. We compared the demographic characteristics, TBI mechanisms, CT scan, surgical procedure, and mortality rate.

Results

The incidence of admissions for severe TBI in Normandy decreased by 33% during the containment. The aetiology of TBI significantly changed during the containment: there were less traffic road accidents and more TBI related to alcohol consumption. Patients with severe TBI during the containment had a better prognosis according to the impact score (p=0.04). We observed a significant decrease in the rate of short-term mortality related to severe TBI during the period of lockdown (p=0.02).

Conclusions

Containment related to the COVID-19 pandemic has resulted in a modification of the mechanisms of severe TBI in Normandy, which was associated with a decline in the rate of short-term death in intensive unit care.

Severely injured patients do not disappear in a pandemic: Incidence and characteristics of severe injuries during COVID-19 lockdown in Finland

Background and purpose - COVID-19 lockdowns have resulted in noteworthy changes in trauma admissions. We report and compare the incidence and characteristics of severe injuries (New Injury Severity Score [NISS] > 15) during the COVID-19 lockdown in Finland with earlier years.Methods - We retrospectively analyzed incidence rate, injury severity scores, injury patterns, and mechanisms of injury of all severely injured patients (NISS >15) in 4 Finnish hospitals (Tampere University Hospital, Kuopio University Hospital, Central Finland Hospital, Mikkeli Central Hospital) during the 11-week lockdown period (March 16-May 31, 2020) with comparison with a matching time period in earlier years (2016-2018). These 4 hospitals have a combined catchment area of 1,150,000 people or roughly one-fifth of the population of Finland.Results - The incidence rate of severe injuries during the lockdown period was 4.9/10⁵ inhabitants (95% CI 3.7-6.4). The incidence rate of severe injuries during years 2016-2018 was 5.1/10⁵ inhabitants (CI 3.9-6.5). We could not detect a significant incidence difference between the lockdown period and the 3 previous years (incidence rate difference -0.2 (CI -2.0 to 1.7). The proportion of traffic-related accidents was 55% during the lockdown period and 51% during previous years. There were no detectable differences in injury patterns. During the lockdown period, the mean age of patients was higher (53 years vs. 47 years, p = 0.03) and the rate of severely injured elderly patients (aged 70 or more) was higher (30% vs. 16%).Interpretation - Despite heavy social restrictions, the incidence of severe injuries during the lockdown period was similar to previous years. Notably, a decline in road use and traffic volumes did not reduce the number of severe traffic accidents. Although our data is compatible with a decrease of 2.0 to an increase of 1.7 severely injured patients per 10⁵ inhabitants, we conclude that severely injured patients do not disappear even during pandemic and stabile hospital resources are needed to treat these patients.

Demand for Essential Nonambulatory Neurosurgical Care Decreased While Acuity of Care Increased During the Coronavirus Disease 2019 (COVID-19) Surge

Background

In times of health resource reallocation, capacities must remain able to meet a continued demand for essential, nonambulatory neurosurgical acute care. This study sought to characterize the demand for and provision of neurosurgical acute care during the coronavirus disease 2019 (COVID-19) pandemic.

Methods

This single-center cross-sectional observational analysis compared nonambulatory neurosurgical consult encounters during the peri-surge period (March 9 to May 31, 2020) with those during an analogous period in 2019. Outcomes included consult volume, distribution of problem types, disease severity, and rate of acute operative intervention.

Results

A total of 1494 neurosurgical consults were analyzed. Amidst the pandemic surge, 583 consults were seen, which was 6.4 standard deviations below the mean among analogous 2016–2019 periods (mean 873; standard deviation 45, P = 0.001). Between 2019 and 2020, the proportion of degenerative spine consults decreased in favor of spinal trauma (25.6% vs. 34% and 51.9% vs. 41.4%, P = 0.088). Among aneurysmal subarachnoid hemorrhage cases, poor-grade (Hunt and Hess grades 4–5) presentations were more common (30% vs. 14.8%, P = 0.086). A greater proportion of pandemic era consults resulted in acute operative management, with an unchanged absolute frequency of acutely operative consults (123/583 [21.1%] vs. 120/911 [13.2%], P < 0.001).

Conclusions

Neurosurgical consult volume during the pandemic surge hit a 5-year institutional low. Amidst vast reallocation of health care resources, demand for high-acuity nonambulatory neurosurgical care continued and proportionally increased for greater-acuity pathologies. In our continued current pandemic as well as any future situations of mass health resource reallocation, neurosurgical acute care capacities must be preserved.

Impact on neurosurgical management in Level 1 trauma centers during COVID-19 shelter-in-place restrictions: The Santa Clara County experience

Early COVID-19-targeted legislations reduced public activity and elective surgery such that local neurosurgical care greatly focused on emergent needs. This study examines neurosurgical trauma patients' dispositions through two neighboring trauma centers to inform resource allocation. We conducted a retrospective review of the trauma registries for two Level 1 Trauma Centers in Santa Clara County, one academic and one community center, between February 1st and April 15th, 2018-2020. Events before a quarantine, implemented on March 16th, 2020, and events from 2018 to 19 were used for reference. Encounters were characterized by injuries, services, procedures, and disposition. Categorical variables were analyzed by the χ2 test, proportions of variables by z-score test, and non-parametric variables by Fisher's exact test. A total of 1,336 traumas were identified, with 31% from the academic center and 69% from the community center. During the post-policy period, relative to matching periods in years prior, there was a decrease in number of TBI and spinal fractures (24% versus 41%, p < 0.001) and neurosurgical consults (27% versus 39%, p < 0.003), but not in number of neurosurgical admissions or procedures. There were no changes in frequency of neurosurgery consults among total traumas, patients triaged to critical care services, or patients discharged to temporary rehabilitation services. Neurosurgical services were similarly rendered between the academic and community hospitals. This study describes neurosurgical trauma management in a suburban healthcare network immediately following restrictive quarantine during a moderate COVID-19 outbreak. Our data shows that neurosurgery remains a resource-intensive subspeciality, even during restrictive periods when overall trauma volume is decreased.

Effects of COVID-19 on the admissions of aneurysmal subarachnoid hemorrhage: the West Greece experience

Background

Acute subarachnoid hemorrhage (SAH) due to aneurysmal rupture is a devastating vascular disease accounting for 5% of strokes. COVID-19 pandemic resulted in a decrease in elective and emergency admissions in the majority of neurosurgical centers. The main hypothesis was that fear of COVID-19 may have prevented patients with critical medical or surgical emergencies from actively presenting in emergency departments and outpatient clinics.

Methods

We conducted a single-center, retrospective, observational study searching our institutional data regarding the incidence of spontaneous subarachnoid hemorrhage (SAH) and compare the admissions in two different periods: the pre COVID-19 with the COVID-19 period.

Results

The study cohort was comprised of a total of 99 patients. The mean (SD) weekly case rate of patients with SAH was 1.1 (1.1) during the pre-COVID-19 period, compared to 1.7 (1.4) during the COVID-19 period. Analysis revealed that the volume of admitted patients with SAH was 1.5-fold higher during the COVID period compared to the pre-COVID period and this was statistically significant (ExpB = 1.5, CI 95% 1–2.3, p = 0.044). Difference in mortality did not reach any statistical significance between the two periods (p = 0.097), as well as patients’ length of stay (p = 0.193).

Conclusions

The presented data cover a more extended time period than so far published reports; it is reasonable that our recent experience may well be demonstrating a general realistic trend of overall increase in aneurysmal rupture rates during lockdown. Hospitalization of patients with SAH cannot afford any reductions in facilities, equipment, or personnel if optimum outcomes are desirable.
